If you have the analogue APC, you can easily modify it. A friend got me to do the one his c900. He got the mod instructions off a board or off the web - I'm sure someone here can help, or maybe hit the search engines. It took me about 20 minutes to do, required a couple of resistors - pennies only.

He also fitted a new exhaust, but the crucial part is an improved downpipe which smooths out the tight elbow. I guess a performance air filter would help too.

When did the DI/APC replace the old analogue APC on 9000's? I always wondered.

"RED BOX" APC and a 3.0bar FPR would make a nice change - I am running a more hardcore box in my 87 - and I love it. There's something up with my Saab tho - i KNow my base boost is still too low (came with 3psi base - it's now like 4....) and when I slapped a box in which held 21psi in a c900 - I only had 9lbs of boost... we turned ALl the settings up and it holds 14 now. So there's something up with my car's system - but it just be that my base boost is way too low. So what the point of that is - check your base boost - should be like 6/7psi with the APC unhooked. You may need to get a boost gauge to do this right. In that case here is where I put mine:
